ACT residents were invited to suggest how Legislative Assembly electoral boundaries could be redrawn for the 17th October, 2020 ACT election. Many suggestions were made and most seem to include various changes to the Brindabella electorate. These suggestion are available for public comment until the 18th March. Then “After considering the public submissions, the Redistribution Committee will publish a proposed redistribution of the ACT into five electorates in mid 2019. People will then have 28 days in which to object to the proposed boundaries.”
